Well, I take an interest in both esoteric and erotic things, but I try not to mix the two (else bad things kinda happens). To me, hypnotism, NLP and such things belong more to the non-erotic, esoteric domain. Hypnotica is a man whose work certainly overlap both fields though, and I can really recommend his Sphinx of Imagination. A few parts of it has some erotic undertones (like moaning women), but most of it is just a cool story. He's also a PUA btw.
Sorry to hear about the break-up (or perhaps it was for the best?). I recall using NLP a lot when "snaring" my second (most long lasting to date) gf (now on no 4) some... Goodness me, 8 years ago now! Time flies :p I was internet dating at the time and the written format really lends itself to "covert" NLP. Today I use NLP mostly for non-erotic purposes (relaxation, memorisation, spritual development etc). I'm happy to share my modest experience with it. Are you mostly interested in using it to get a girl or to showing her a good time once she's hooked, or both?
